Abstract
|
This paper introduces finite difference delay modelling (FDDM) for computing the shield ing effectiveness (SE) of a conductive enclosure with an aperture against electromagnetic pulses. FDDM offers optimal accuracy and stability for analysing complex structures. The time domain electric field integral equation (TD-EFIE) for the conductive enclosure is derived by imposing boundaryconditionsontheperfectelectrical conductor (PEC) surface in the Laplace domain. Time discretization is based on finite differences, and the Laplace to-Z transform mapping is utilized. Fast Fourier Transform (FFT) is employed to expedite the FDDMsolution process. Both frequency domain shielding effectiveness (FD-SE) and time domain shielding effectiveness (TD-SE) are evaluated using this approach. Finally, to validate the accuracy of the proposed method, results are compared with simulations using CST-MWSsoftware and the frequency domain moment method
